The region in the altitude f rom 4400 to 4600 meters , which is mainly covered by alpine meadow and alpine swamp meadow , is st rongly degraded by the stock raising with it s influence radius of about 24 kilometers. The influence distance perpendicular to roads is also 24 kilometers , since road const ruction accelerates human2induced destruction to vegetation. Vegetation in shade aspect is rising due to the increase in precipitation , while vegetation in sunny aspect tends to be stable or degraded because of the enhancement in sunlight . Furthermore , the vegetation coverage is influenced by the groundwater level . In near riverbed fields , where the depth of groundwater is shallow , plant s can easily grow ; while in far riverbed fields , vegetation is prone to degrade due to drainage. The radius of river influence is 24 kilometers.

海拔4400～4600m的较低海拔地带退化最强烈，主要为高寒草甸与高寒沼泽草甸受牧业影响较大；牧业影响半径为24km；道路的影响范围为24km，道路的修建加速了人类对高原植被的破坏作用；阳坡植被呈现趋于稳定和退化的趋势，阴坡植被表现为增长的趋势，降水量增加是源区植被，尤其是阴坡植被变好的重要原因，而太阳光照增强是导致阳坡干旱和植被趋于退化的潜在原因；近河床区地下水位埋深较浅，植被生长具有稳定的地下水源；在远离河床的一定区域内，地下水易于疏干，植被易于退化，河流影响范围为24km。

The research work done is presented as follows:Compound dewatering technique of vacuum tube well is an effective technology for solving the dewatering problems of aquitard and interface relict water according to physical simulation test and field test. The variation laws, such as degree of vacuum, pore water pressure in different strata, have been studied. The results show that there is a certain scope of influence of vacuum in strata, and the vacuum degree in the horizontal direction decreases gradually with the increase of the distance from the main well; the change law of degree of vacuum in the vertical direction increases firstly and then decreases with the depth of soil strata, and changes with different soil nature and depth; changes of pore water pressure in soil strata has also shown a similar law of degree of vacuum.

主要研究工作如下：通过室内物理模拟试验和现场试验均证明了真空管井复合降水技术用于解决弱透水层和界面残留水疏干难题的有效性；并且对不同地层中真空度、孔隙水压力等变化规律进行了研究，发现地层中真空度均有一定的影响范围，且真空度在水平方向上随距主井距离的增加而逐渐降低；在垂直方向上真空度随深度总的规律是先增加后降低，并随土层性质及深度的不同而变化；土层内孔隙水压力也呈现出与真空度类似的变化规律。

Moreover, during the radar signal generation, static and dynamic characters of backscattering coefficient are set up, and time sampling of each clutter unit is computed with voltage character and power spectrum character, and the sampling signals are added in every distance gate to output time series. In addition, noise is modeled with a function of Gaussian stochastic process.

在雷达信号模拟中，建立了杂波后向散射系数的静态和动态特性，从杂波的幅度统计特性与功率谱特性入手，计算了每个杂波单元的时域采样，按照对应的距离门叠加各个距离模糊间隔上的回波信号并形成时间序列，并采用一个高斯随机过程的样本函数来表示噪声模型。

A large number of subjects in the following interview prefer distance cue due to its comprehensibility of proportional scale. The direction should mark toward the north, and sign marking left or right turn has no practical meaning in use. Route cue and touch time have no significant difference, and however, for the visual impairs, positive assistances are found in memorizing route.

在后续的受测者访谈中，多数受测者偏好使用距离标示，因为此标示可以增进比例尺的概念，方向标示应该使用指示北方的方式，左右方向的标示并无使用上的实际意义，路径标示虽然在触摸时间上无显著差异，但是，对於视障者理解并且记忆路径有正面的帮助。

Based on the established GIS of the Oncomcelania Snails' distribution in Dongting Lake, the author analyzes the environmental condition of the Oncomcelania Snails' habitates comprehensively by the spatial analyzing technology. The results are as following: firstly, the predominant vegetation of Oncomcelania Snails habitat is reed and sedgy. The habitats with reed has a higher livability than with sedgy as dominating vegetation. However, the diffusion of Oncomcelania Snails is much serious in the habitats with sedgy. Secondly ,the predominant soil type of the Oncomcelania Snails breeding area is temporary submergic paddy soils, which is in weak acidity environment, of that PH value is 5.5--7.5, and the organic content is in 2---3%. Thirdly, the 80 percent of the Oncomcelania Snails breeding area, the normalized difference vegetation index of that is in 0.100-0.375%, and the soil humidity of that is in 0.202—0.507, and the distance to the water of that is in 10-230 meters.
